Selective precipitation of ions in a mixture in the form of salts can be adding common ions gradually. Let us condsider selective precipitation of CI^(-) and CrO_(4)^(2-) ions in the form of AgCl and Ag_(2)Cro_(4) form a mixture having having 0.01M CI^(-) and 0.01M CrO_(4)^(2-) . For this, salt having Ag^(+) [like AgNO_(3)(s) ] is added gradually. Given : K_(sp) [AgCI]=10^(-10) and K_(sp)[Ag_(2)CrO_(4)]=4xx10^(-14)] The percentage of one ion precipitated when another ion starts precipitation is : (Given: (1)/(sqrt2)=0.7 )
